Subject: [PATCH 2/6] refs.c: Fix a sparse warning

From: Ramsay Jones <[email-masked]>
Date: Sun, 06 Oct 2013 21:49:18 +0100

Sparse issues an "Using plain integer as NULL pointer" warning
against a call to update_ref_lock() which passes '0' to the
'int *type_p' parameter. In order to suppress the warning, we
simply change the argument to 'NULL'.
